The soil reference value is expressed as a percentage of density These values are determined before any compaction takes place to develop the compaction specifications Modified Proctor values are higher because they take into account higher densities needed for certain types of construction projectsSep 14, 2019 compaction factor is level of compaction we achieved compare with a standard value which we had achieved in lab testing Calculation of moisture content in the sample also an important parameter, if the value calculated goes wrong, it will also impact on the compaction factor calculations When we find there is something wrong happened in doing Compaction factor of Soil Civil4MDec 26, 2014 The degree of compaction is the basis and or the final acceptance once it is passed The specification commonly says “The degree of compaction shall be not less than 95 percent of maximum dry density (MDD)”How To Calculate A Compaction Test ReportValue of Max dry density (MDD) = 2221 gram/cc = 2221 Kg/ cubic metre Compaction Factor = (MaxDry Density/Density of Blended Aggregate ) =2221/ 170 =1307 = 130 Hence compaction factor = 130 3 How much loose thickness of GSB should be taken to get proper compacted layer thickness ? Compaction factor Granular Subbase Base (GSB) quantity / Compaction Factor The compaction factor test is carried out to measure the degree of workability of fresh concrete with regard to the internal energy required for compacting concrete thoroughly The compacting factor test is used to find out the low workability of concrete it is a Compaction Factor Test Of Concrete, Result Calculations

Sep 14, 2019 compaction factor is level of compaction we achieved compare with a standard value which we had achieved in lab testing Calculation of moisture content in the sample also an important parameter, if the value calculated goes wrong, it will also impact on the compaction factor calculations When we find there is something wrong happened in doing better laboratory methods of establishing a density standard on which to base compaction control specifications n the common factor W is cancelled out, the desired term D may be found: by substituting the proper values in Eq 3 This plot is shown as Curve A in Figure 1Suggested Compaction Standards for Crushed Aggregate The compaction factor test is designed for use in the laboratory but it is also used in the field This test is more sensitive and precise than the slump test It is particularly useful for concrete mixes of very low workability and generally used when concrete is compacted by paction factor test Objective, Procedure, advantages Dec 27, 2014 This is a continuation of the previous article I posted How to do a compaction test or Insitu density test, about the calculation of the compaction test report Here we are going to compute the bulk density of sand down to the degree of compaction of soil I would really want to pursue this article just to completely show the full process of getting the results of the test from taking the How To Calculate A Compaction Test ReportThe Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry densityThe test is named in honor of Ralph Roscoe Proctor [], who in 1933 showed that the dry density of a soil for a given compactive effort depends on the amount of water the soil contains during soil Proctor compaction test Wikipedia
Compaction and Measuring Pavement Density Pavement
Sep 15, 2010 Compaction’s importance Compaction is how proper density is achieved Compaction is typically expressed as “percent air voids” In many mixes, a denser hot mix pavement leads to a higher quality pavement, so density values are often used in industry to pay or penalize paving contractorsSep 04, 2008 you are only testing at a few spots and compaction will vary the standard deviation with 95% requirement might only give you 90% in some areas which may not be acceptable With 98% requirement, the standard deviation is reduced and your minimum values of compaction may come closer to the the 95% that you are looking forWhat is the difference between 95% and 98% Proctor Compaction?Sep 26, 2013 Swell is expressed as a percentage of natural volume, for example, if 10 yd 3 in the ground becomes 13 yd 3 after excavation, the swell factor is 30% The following table lists swell factors for various engineering materialsSwell Factors for Various Soils ProjectEngineerCalculation of Compaction Factor Value The compaction factor is defined as the ratio of the weight of partially compacted concrete to the weight of fully compacted concrete It shall normally to be stated to the nearest second decimal place Compaction Factor Value= (W1W) / (W2W) Result of Compaction Factor Compaction factor of the concrete =Compaction Factor Test for Concrete Workability Method The test consists essentially of applying a standard amount of work to a standard quantity of concrete and measuring the resulting compaction The compacting factor is defined as the ratio of the weight of partially compacted concrete to the weight of fully compacted concrete It shall be stated to the nearest second decimal placeLab Report for Compacting Factor Test » Civil Engineering

Fundamentals of Soil Compaction
Figure 4 Effects of compactive effort on compaction curves It can be seen from this figure that the compaction curve is not a unique soil characteristic It depends on the compaction energy For this reason it is important when giving values of (γdry)max and mopt to also specify the compaction procedure (for example, standard or modified)Maximum compaction occurs when there is no water in the soil so this helps understand how the existing water is affecting the compaction efforts Step 4 Dig a small hole into the soil, approximately 6 inches by 6 inches, and remove the soil for the and cone test as the proctor test is being done at the labHow to Calculate the Soil Compaction Factor HunkerSep 15, 2010 Compaction’s importance Compaction is how proper density is achieved Compaction is typically expressed as “percent air voids” In many mixes, a denser hot mix pavement leads to a higher quality pavement, so density values are often used in industry to pay or penalize paving paction and Measuring Pavement Density Pavement Standard Practice for Compaction of Prismatic Asphalt Specimens by Means of the Shear Box Compactor Standard Practice for Calculating Precision Limits Where Values are Calculated from Other Test Methods Standard Practice for Developing Axle Count Adjustment Factors: E2468 05(2018) Standard Practice for Metadata to Support Archived Road Standards and Paving Standards, each with a minimum factorofsafety of [select FS based on design analysis] Use, maintain and control, compactorsoillift combinations sufficient to achieve these properties for each lift as approved by the engineer Compact each lift with the minimum # of passes producing full asymptotic compaction with the compactor used on siteExample Recommendations for Compaction Specifications
